Applicationfiled November '4, 1909. Serial No. 526,222.

Be it known that I, EDWARD Posson, a

citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and use fulImprovements in Movable Bulkheads for Refrigerator-Cars, of which thefollowing is a specification.

My invention relates to movable bulkheads or partitions for refrigeratorcars by the use of which ice chambers may be partitioned off fromthemain part of the car at the ends. The bulkheads may be displaced whendesired so as, to make the entire interior space in the car availablefor freight. The objectof my invention'is to improve the construction ofbulkheadsiofthis character in various respects, one of which consists ofa series of guideways in the sides of the car which have downwardlyturned the bulkhead in either of its positions. Convenient and simplemeans for raising the bulkhead from the. depressed ends of the guidehave been provided, as well as rollers anda track on which it may beeasily moved from'one positionto another. v 1 Another object consists ofproviding means for supporting the grate on which I pivoted to the car.frame.

the-ice is carried and which permits easy whichthe grates are supportedat one of heir ends, the otherend of each grate being Another featurecomprises stops in the V fioorof the car into which thevertical postsfof the bulkhead frame are lowered.

Other objects and advantages will be apparent in the specification andclaims, taken in connection with thedrawings', in whichj Figure 1 is across sectionof a'refrige'rator car' body showing a view in elevationwith-parts broken awayof one of the bulkheads. Fig. 2 is alongit'udinalvertical section of one end of the car showingthe bulkhead in crosssection. Fig. 3 isa horizontal section of one end of the car showing thebulkhead in section and ajportion' of the grates. Fig. e'is a detailshowing one of .theupper corners of the bulkhead and tho particularlytheshaft and rollers by which adjacent parts of thecar body and showingthe bulkhead is. elevated. 'Fig. ;5 is a side view of the same. Fig.6-is a perspective view of one of the pivoted bails' withpne of thegrate bars resting thereon and also one of the retaining hooks for saidbail in its proper relative position to said parts. Fig. 7 is aperspectiveview of the lower end ofone of the right-hand members of thebulkhead showing a device for engaging the stops in the perspective view'of one of the frame members.

floor; Fig. 8 is a perspectlve view ofone of said stops. Fig. 9 1s a Inthe drawings, the reference numeral 16' designates the outer uprightframe memupper ends Near the bottom of the bulkhead is the horizontallydisposed Z-bar 20. In the central web 20 of the Z-bar are vrectangularapervtures 20 through. which the vertical posts '17 are placed. Theshorter posts 18 .rest at their lower ends upon the web 20 of theZ-barand are fixed to the said Z-bar by" means of the bolts 18 The Z'baris recessed atits outer end 18 to permit the insertion-of the outerposts 16. In the body of the bulkhead the deflecting devices 20 for theair current are placed between these upright posts and are not describedin detail herein because they donot form a part of this invention. Thenetting 21 is placed against the said posts on their inner faces. Theslats 22 are fixed to the front faces of the posts and protect the otherdeflecting devices 20. A horizontally pivoted door is provided atthe-bottom of the bulkhead.

This door comprises slats 23 which are fixed to hangers 24 which in turnare pivoted at 25 to links 26. These links in turn are pivoted to eyes27 which-are fixed to the"vertical flanges 27 of the Z- bars 20.

The above described bulkhead is'spa'ced a considerable distance from theend wall 28 of the car and in the space thus provided the ice isdeposited.

The bulkhead is provided at its upper edge with a horizontal shaft 29which is pivotally supported thereon by the bearings 30 fixed to thechannel bar 19. The shaft 29 is. provided with crank arms 31 preferablyintegral with said shaft, and in the ice'to rest upon in-th'elowerportion'of the I outer extremity of said arms 31 the shaft 33 siderabledistance.

is mounted. A roller 32 is fixed'tokthis passes through the lever andhas a bearing 1' therein. -The shaft 29 may be rotated by means of thislever andby means of the .eccentrically attached roller 32, above described, the bulkhead may be raised a conhook 36 attached to thebulkheadprovides means for retaining the lever 36 in an oper- *ated position inwhlch position the bulk-.

head is carried upon the track 34 by the rollers 32. Another hook- 37provides means for holding the lever 36 in its unoperat'edpositionadjacent the root of the car.

The guides 38 are provided in the walls of the car and serve'to guidethe bulkhead between its two positions, one of said posi- I 'tions beingthat shown in the drawings in which-aspa'ce is separated off for anicechambnthe other of said po'sitions being adjacent the end wall of thecar. .These guides have a, channel-shaped cross section of rectangular,form'in which the ends of pins 41 are made to operate. The ends of thepins 41 areprovided with heads 42 which lie within the retaining flange43of thelsaid the ends with downwardly extending guides 38. The. guides38 arefprovided at tions or ofl sets 39. The pins 41 drop 1nto thesedownwardly extending port-ions 39 in either position of the bulkhead andthe bulkhead is thereby securely retained in posi-- tion. In order tomove the bulkhead from of the parts related thereto.

v-downwardly extending portions 39 of the one position to the other-litis necessary to first raise it by means of the lever- 36 as will beclear. from the previous description When thus ra-ised -the bulkhead isfree tofslide along the. gu'ide 38 to. the other position. The

guides are provided with the short retaining guard 40 at their lower andinner faces. The guides are securely heldin position in the walls of thecar by means of bolts 45,

46, etc;- The.sheetimetal lining 46%"- iscut away around the guides 38and is made to lapover the upper edges 43 and-to lie within theloweredges 43 0f theguides 38.

-The ice grates 47 are provided for the ice chamber and are pivoted atone edge to the hooks-49 which are bolted to the end wall of thecar.Thespacing thimbles 48 serve as means for making. this pivotal conneo{age by the pressure of the ice;

When thus raisedv its weight is'transferred to the. tracks 34. A

tion. The, said grates 47 are composedof bars which are spaced bythimbles '48.- The grates 47 are given an inclined position'as shown in'the drawings for the purpose ofcausing-the blocks of ice to move awayfrom the bulkhead and against the end 28 of the car body. By this meansthe 'bulkhead is protected'in-a' largemeasure against dam- 1 The grates47 arecomposedpf independentsections which form a-series whichliestransversely of the car at the bottom;

of the ice chamber.

The separate ends, of

the grate sections are supported by the swinging bail 51, which ispivoted'at 52 tothe underside of the Z-ba-r 20. The grate barsare-"notched at their ends as shown at 50 a where they rest upon thebail 51.. The down wardly projecting and. outwardly curved 1 8 5 tongue53 is provided on'each'bail and serves as a means byxwhich the grate bars may push the :bail' out of'the way momentarily when the grates arebeing raised to their inclined positions. The grate sections' a r'eadapted to drop into the'pan' 57' at thejbot tions and when thesectionsare lowered their upper surfaces are therefore in the same planewith the floor of the-car; The bail 51 is retained inp'osition belowtheelevated end'of the grate sections by thehook 54 which is pivoted onone of the spacing thir'n bles 48. It is prevented from dropping down toan excessive degree when not en-v gaged with the bail by anotherof thespac-- ing thimbles. The pan. 57 is provided with a depressed portion 58and in this depressedv portionis a further depression 58? in which-- isplaced the trap 59.. The trap 59 retains a small portion of the waterbelow the level of the end of the outlet pipe 59, thus iseal frhm theoutside of the car; r The extended lower ends 61 0f the upright 'framemembers 16 and l7.;rest upon,- the"- bottom of the pan57 adjacent-{theinner edge ing the ice chamber against admission- 0f air ire where saidpan lies against the floor (SO'otthe car. Near the lowerend ti'l'of thesaid upright frame meinbersis a :short barf63 which is adapted toengagethe 'sto p-'62 in -fl' the floor of the car. .Thisstop 62 is a hollowmetal device into which the bar 63proje'cts.

When the bulkhead-is lowered intoxfposi-tion thebar 63 enters the recessin the stop 62. The operation of my. improved bulkhead .has already beenlargely referred to throughout the preceding'portion of the spee'ificm'tion. I It may be further said that the bulkhead may be very quicklyand, conveniently moved from theposition shown in the drawings to aposition adjacent th'evendiof the car by first pulling downwardly uponthe lever 36, which raises thebulkhead adis tance equal to thedepth ofthe downwardly" y tom of the -ice chamber. The depth of this pan isequalto the depth of the grate sec'- extending portions 39 of the guides38. This heads 42 of the pins 41 are free to slide along the guides 38to'the other extremity of sai guides and when inthe latter position thelever 36 may beallowedto rise to aposition adjacentthe ceiling of thecar. By this movement. of the lever 36, the bulkhead is the end wall ofthe car.

into the downwardly extending portions 39' bails. 51 which are suspendedfrom. the Z-bar permitted to settle into a position adjacent The pins 41drop of the guides 38 andhold'it in that position.

IThe return movement of the bulkhead to its former. position may ofcourse beefiected in a similar manner. If it is desired toretainthe/bulkhead in a supported position while being moved from onepointto the other without effort on the the lever 36 may on thebulkhead; V V

Both rollers 32 at the endsof the shaft 33 being keyed thereto the lateral edgesof the bulkhead are caused to move at the same speed and noattention is required of the operator in causing the bulkhead to moveupwardly into position. i

When the bulkhead is used as a partition as abovedescnibed and a-n'ic'echamber is thereby divided off, the ice may be dropped into saidchamber. in the usual way through a hatch in the roof of the can. Theice be engagedby the hook'36" would fall upon the grates??? and theweight of said ice would be carried partly by the 20 and partly by thehooks'49. If it is desired to remove remnantsof ice in the ice chamberbefore moving the bulkhead to a position adjacent the end of the car,the

grates't'? may bedropped into the pan 57. In doing this the retaininghooks 54 would be first raised after which thebails 51 may be easilyswung out from beneath the ends of the grates. i In view of thefactthatthe ice grates are.;made in sections it would be clear that oneonly of these sections may be lowered at a time and the i'ceat anyparticular part of the ice chamberma be removed. The gate 23 would ofcourse eqraised out of-the way when removing the ice. The link 26 servesan important function when thus raising the gate as it permits the pivot25 to be swung out of a vertical line below the'pivot- '27., Thispermit'sthe gate 23 to be fully swung around to a vertical position vagainst the slats 22 of the bulkhead Thefdownwardly curved tongues 53 onthe bails 51 are very convenient for. the operator to seize for thepurpose of swinging the bails 51 out of engagement with the ends of thegrates 47. 'Their forwardly projecting position causes the handof theoperator to be out-of the path of the falling grates They.

upon the floor and part of the operator,

as a partition for dividing otf space as an ice chamber, the lower end61 of the upright members of the bulkhead frame drop into their properpositions in the forward part of the pan 57, and the bars 63 enter therecess of the'stops 62 without any attention on the part of, theoperator.

"The-bottom of the'pan is below the level of the floor 60- and it willbe clear thatthe Water in said pan cannot find, its way out causedamageto the contents in the car.
